Question

Explain why crinoid fossils can be found on the shore of Lake Michigan, which is a fresh water lake.

Answer 1

Step-by-step explanation:

Crinoid fossils can be found on the shore of Lake Michigan because during the Carboniferous period, all of what is now the United States, except for a small part of the upper Midwest, and all of the states along the East Coast, except for Florida, was covered by a warm, shallow inland sea(seawater), and since crinoid fossils live in sea water, they washed up on many places like Lake Michigan.
